non-working dmesg
dmesg for machine that doesn't work.
Can you try with gentoo-test-sources? I'm pushing for that to move to gentoo-sources soon. Yeah, 2.4.22 vanilla obviously has support for such things, but I'll see whether this is backportable. 1) I don't see the revelant log portions for the non-working kernel, can you attach relevant portions for both kernels? 2) Can you also attach /proc/config from each kernel? Thanks... Created attachment 21097 [details]
Log entry for non-working machine
This is section of /var/log/everything/current when I plug the device into the
non-working machine.

Log entry for working machine
The log entry for the working machine (starting from when I plugged the device
in)
I don't have /proc/config on either machine; would you like /usr/src/linux/.config? I should note that the laptop (working machine) has been able to access this device since 2.4.20-vanilla. Tim Yamin sent me an e-mail; I'm reproducing it here, with my answers, to keep everything in one place. >Is it by any chance http://usbat2.sourceforge.net/ as that's the relevant USB >vendor ID? That's not it, although it may run on the same chipset. Mine bills itself as a 'ZiO!' somethingorother. >Yes, I did mean the /usr/src/linux-.../.config; sometimes kernels have >/proc/config and that is more accurate incase something got modified and out of >sync with the file .config.

Working kernel config (2.4.21)
It would appear that I mis-spoke earlier; it seems the working machine is running 2.4.21, not .22. Can you please enable CONFIG_USB_DEBUG on the faulty kernel and see if anything useful comes out... Also try CONFIG_USB_STORAGE_DPCM. Thanks. So, rebuilt the desktop machine's kernel with genkernel yesterday...and it works now. gentoo-sources-2.4.20-r9. May as well close this. Closing as this seems to be resolved. |
